"Saturday Night Live" is a treasured cornerstone of American television, and it's almost hard to believe that, on September 27th, the show will make its 40th season debut.

Now, we're going to assume that premiere host Chris Pratt has been an absolute gentleman in the week leading up to the premiere -- his SNL promos are charming as ever -- but it should be noted that there have been more than a few hosts (and musical guests) who've made a mark on the series in a not-so-positive way. So, to celebrate the show's 40th anniversary, we've compiled a short list of stars who've earned a special, dishonorable place in "Saturday Night Live" history.
